I looked in the tech write up section for a guide to cleaning a throttle body, but there isn't a write-up. I did a search and read related topics, but I'm a totally newb when it comes to anything much more than changing my oil and maintaining proper fluid levels.

Is there anyone that would care to atleast give me a quick guide on what I'll need to do? If there's anyone feeling really wild a full blown write up would be even better, but beggars can't be choosers...

Thanks for any help you can give,

T-body cleaning Ask and you shall recieve.

 

Here is a link that may help. It is for Tacoma's, but I'm sure the principle is the same:

Thank you both for the links, I knew ya'll would come thru for me.

In addition to the methods above, I like to spray the cleaner in there while the engine is running.... Normally it won't run with the mass air-flow sensor removed, but since the 2nd gen has a flap type, I simply had my son hold that flap open a little, so the engine thought it was getting some air in, and then I sprayed the TB cleaner directly in the intake while it was running, for a little extra DEEP cleaning.

Maybe for a 3rd gen DEEP clean, they could hook up to a shop vac or something....

 

Okay, I cleaned it out today and I didn't have any problems. I used a carb cleaner and a toothbrush. There was some black dustyness, but I had expected there to be more "gunk". I cleaned back into about 2 inches behind the flap, but that's as far as I could reach the toothbrush without it being too far in to maintain control and good leverage. Is that all there was too it?

I drove to the store earlier tonight and didn't notice any change in response to acceleration. It kinda makes me wonder if I did it right.

Oh well, next weekend I'm replacing my fuel filter (money permiting).

I just cleaned mine. I wasn't sure it needed it since I bought the vehicle used last year-97 2.7L Tacoma 4X4 with 120K miles.

I figured it was probably due. I was skeptical about doing it at first, but shortly into the operation, I realized that its a fairly simple process. My only real problem was the airbox. I was able to remove the nuts underneath easy enough, but the box was stuck on one side. After some gentle coaxing with a screwdriver, it came loose.

Initially I thought it was pretty clean, but then I noticed that it was very black behind the flap. It took me a while, but I got it pretty clean by spraying, wiping, and using the toothbrush. I even jacked the driver side up pretty high so the throttle body would be pointed slightly down. That way, whenever the dirty carb cleaner accumulated in any noticeable amount, it would run out onto a rag I had under the opening.

I think it may have helped some. I'm almost pretty sure it did a little, but if it had been cleaned without my knowledge, I would probably not be able to tell.

Now, if I can just get up the nerve to try and change that fuel filter.
